Students will explore the Law of Conservation of Energy by reviewing common forms of energy and how they may be converted to other forms of energy. Students will be guided through this exploration by a PowerPoint presentation reviewing the basic forms of energy and how they may be converted.
The students will then conduct a lab activity where they build voltaic piles utilizing copper pennies, zinc plated washers, and salt water soaked cardboard. Students will use a voltmeter to record the voltage produced by their voltaic piles, and will experiment utilizing the voltaic piles to power small electronic devices such as LED lightbulbs or flashlights, calculators, piezo buzzers, etc.
Students will then complete five (5) Lab Journal Activities/Questions in their Lab Journals, and one Real World Challenge question on a separate sheet of paper. The Real World Challenge Question will challenge the students to apply the knowledge gained from the lesson to a life or death real world scenario.
